Do you have some electronics you'd like to protect from an EMP (electromagnetic pulse) or a solar storm like the Carrington Event of 1859*? You need a Faraday cage.
You can find instructions for building one (or several) online, but here's what I did.
I took an old steel shortening can (from decades past) and completely lined it with cardboard; sides, bottom, and under the lid. I sanded the rim and inside the lid to make sure the connection is electrically conductive. Then I tested it with radios (including a cell phone). No signal was getting through, so it should be OK. Or, that's the information I was able to find.
To do this effectively you have to have spare electronics. If you have an emergency radio that you are using when the EMP hits, having a Faraday cage to place it in did you no good. So have an emergency radio you use and one you store, protected.
Inside mine I placed a solar charger, a USB battery charger which can use the solar charger, walkie-talkies, an emergency radio, some lithium batteries (non-rechargeable, but good for long-term storage and they won't leak), flashlights, etc. Most things I've read said batteries won't be harmed by an EMP, but even so, having batteries stored with these items seemed like a good idea.
If you have more, or larger, items you want to protect you could use a metal trash can or other large metal container as the basis for your Faraday cage. I've seen some military surplus cases (for RPGs maybe?) that look like they would work well once properly modified.
Find out all you can, make one, and test it to the best of your ability before trusting it to do its job. It's just a little extra insurance, but it could make a big difference if it is ever necessary.
If you focus only on guns and ammo, you are not prepared. If you focus only on stockpiling food, you are not prepared. If your focus is too narrow on anything, you are not prepared.
Prepping means you are trying to be ready for whatever comes. You don't know if it will be a xombie apocalypse or just a supply chain collapse. You have to be ready for either one-- and both at the same time. You have to be ready for a failure of anything you need for survival, without regard to "why"-- just that it is happening.
You can't foresee everything that might cause there to be no food available to buy, but you can do things to make sure you'll be OK. You can't predict what might cause hordes of predatory creatures to swarm your property, but you can be ready to defend against them, whoever and whyever they are there. You can't know for sure why there's no electricity in the grid, but you can make sure it's not a problem for you.
Prepping is the responsible thing to do. If you are prepared you ...
You don't have to outrun the bear; you only have to outrun your hiking companion.
Yeah, that's a cynical way to look at it, but there's truth in it.
With prepping (in the event of TEOTWAWKI), you may not have to survive on your preps until you are 90 years old, just outlast those who didn't prep. Once they die off, survival may get easier.
I know-- it would be great if you were able to keep everyone alive into the distant future. But that's just not going to be possible, is it?
Once the marauders and beggars have Darwinized themselves out of the population, it will be easier to grow your own food. You'll only have to worry about deer and raccoons, not Naked Apes (which is a really good book by Desmond Morris, by the way).
So, while it would be nice to have preps to last until you die of old age, and be self-sufficiently growing your own food, making your own soap and cloth (or buckskin), realistically, at least have enough to outlast those who would be the biggest threat to your ...
I've been doing something non-prepping this past week. Maybe even anti-prepping, as in it may be a step backward.
I rescued a kitten who found me along my morning walk. He was about 5 weeks old, sick and starving, and was barely able to come toward me. I couldn't ignore his cries for help.
So I've been spending money I don't have to spare-- and just about all my spare time and energy-- bringing him back.
And it's working.
He's still got a respiratory infection and eye infections, but I've got him on antibiotics and he's improving. He's eating and playing really well. No longer is he skin and bones; I can pet him without feeling every vertebra and rib.
Sometimes you've got to do the right thing even if it's not smart.
